Canon i-SENSYS MF4780w - Performance

Canon rates the i-SENSYS MF4780w at 23ppm, which is a very respectable speed. Under test, we got quite close to this, with a maximum speed of 19.7ppm from the 20-page text print. The five-page tests gave 15.0ppm and 13.6ppm for the text and text and graphics documents, respectively. A 15 x 10cm photo on an A4 sheet took just 10s.

The spec sheet also claims fast first page out and this was reflected in the speeds we saw for our copy tests. A single page copy from the flatbed glass took an impressive 10s, while five-page copy from the ADF completed in 25s, which is again very quick.

Canon i-SENSYS MF4780w - Open

The quality of those fast prints is very good, with black text coming out particularly sharp and well-defined. Greyscale graphics show no banding, though there is a slight problem with the different colours producing the same greyscales – this can be a problem with colour-coded charts, for example.

Copies of greyscale originals showed considerable blotchiness, though no worse than from other CIS scanners. A photo print was reasonably smooth for a mono laser print, though darker shades were nearly black.

Although the measured peak noise level for this machine was 62dBA, this doesn’t reflect the sustained noise which, subjectively, is quite high. Particular when copying, it really isn’t a machine you’d want to talk on the phone next to. Perhaps this is a reason for Canon including a quiet mode. Quiet mode reduces the noise level significantly, by running the print mechanism more slowly.

Canon i-SENSYS MF4780w - Cartridge

The drum and toner cartridge is only available in one, 2,100 page capacity and, at the best price we could find, gives a page cost of 2.9p, including 0.7p for paper. Anything below 3p per page from a laser is reasonable, though 2.9p isn’t the best price we’ve seen from this class of machine.


The Canon i-SENSYS MF4780w is a good, wireless laser all-in-one. It prints quickly, though has no duplex, and produces very good text and above average graphics and costs under 3p per page to run. It’s a bit noisy when printing, but has a slower, quieter mode, can connect wirelessly to a network, and can print to mobile devices.

It would be a lot better if you did not have to press anything on the scanner to scan something from your computer.

Mine simply stopped working. LCD light is on but stuck on "current date and time". Won't budge. Tried everything.

Canon i-SENSYS MF4780w Review

Only my opinion: CANON all-in-one scanner is not for professional jobs. It scans only the entire page, without allowing to select the area to be scanned. Although it has many options and functions, they don't help much. My old HP scanner scans everything on its screen but then the software allows to select exactly what I want to scan by cutting out it from the entire page and its simple to use. Not the CANON. This one CANON does not seem to have that functionality. It only scans full page
documents, but if one wants to scan a business card one has to use PAINT or other software to cut the detail out of the entire scan. Also the scan quality is so bad even at 300 dpi I can see the coloured streaks and lines in many locations on the image and when image is reduced it looks horrible with CANON.

Just my opinion. This is why I want to keep on using my old scanner as long
as it works and if it breaks down, I will have to buy a scan-alone scanner. This CANON good as copier only and to scan some unimportant documents. Keep that in mind when your new customer asks for a professional high quality scanner. But it still is ok as a copier and probably a fax as well.

It also has problems restoring date and time settings after a thirdworldly power cut in Portugal. It never saves date and time. I have to re enter everything again and again. Yet after its been in the repairs, it suddenly saves the date and time, I think it does now! At least sometimes! PROGRESS!

Also, about 7 months after purchase my CANON just stopped working. PLANNED OBSOLESCENCE at work.

You know what I did last year? I bought an old typewriter for $20 and have been happy ever since. Never will buy any piece of electronics, battery etc. ever again. Not even a light bulb!
